Therefore, the notion that the power will be set "when all the competitors have put their cards on the table" is nonsense. Competitors never put all their cars on the table. There's always something better coming, so as a business you don't wait around until the last minute waiting to release your product. You do your best to pick a target, and then market the pants off of it once it is ready.
What was the power/weight improvement for the E60 M5 to the F10 M5? I would expect the F80 M3 to see about the same percentage-wise vs the E90 M3.
According to post #2, it was 4%. If we go by that, and assuming the next M3 is lighter, then it would be around the same if not less hp than the current model.
